Witness Information Checklist

Key Takeaways

• Witness contact information collected at the scene is recoverable. A witness who leaves without being identified is not.
• You need a name and phone number, not a full statement. A formal statement can be taken later by an investigator or attorney if needed.
• Note where the witness was standing when the incident occurred. Vantage point affects how useful their account will be.

Who counts as a witness

Anyone present who may have observed any part of the incident or its immediate aftermath can be useful: occupants of other vehicles, pedestrians, cyclists, nearby property owners or employees, and other truck drivers in the area.

Witnesses don't need to have seen the collision itself to be relevant. Someone who saw a vehicle run a red light before impact, or who observed road conditions before the crash, provides useful information even if they didn't watch the collision.

What to collect from each witness

Full name and a phone number they can be reached at. Their location at the time of the incident — on the corner, stopped in the adjacent lane, working at the dock across the street. A brief note of what they say they observed, in their own words as closely as you can capture it.

Ask 'what did you see?' and write down the answer. Don't ask leading questions or prompt a particular account. A witness account that was clearly shaped by the person collecting it carries less weight.

When witnesses won't engage

Some people won't stop or give contact information. If a potential witness is leaving, try to photograph their vehicle's license plate. A witness identified through a plate trace is slow but possible. Don't pressure or obstruct anyone — note what you can and move on.

A vehicle description and plate number, combined with a note of where the vehicle was positioned, may be enough for later identification if the claim warrants it.

After the scene

Pass all witness contact information to your company safety contact and insurer as part of the incident report. Don't reach out to witnesses again independently without guidance from the claim contact or legal counsel — witness communication in an active claim should go through proper channels.

Note in your incident report which witnesses were identified, their contact information, and what they said at the scene. If a witness gave a particularly specific or potentially problematic account, note that for the safety contact.
